Abstract


The redox transformations of trinuclear phenylvinylidene  CpReFePt(µ3-C=CHPh)(CO)5(P-P) [P-P = Ph2P(CH2)nPPh2, n = 2 (dppe), 3 (dppp)]clusters were studied by electrochemical methods at platinum, glassed carbon, and dropping mercury electrodes in acetonitrile solutions. It was established that one-electron oxidation of the clusters results in formation of the binuclear Cp(CO)2RePt(μ=C=CHPh)(P-P) [P-P = dppe, dppp] complexes and Fe-containing fragments.
